2 Safety and Maintenance Guidelines

Important Safety Information

A power cord is included with the monitor. If another cord is used, use only a power source and

connection appropriate for this monitor. For information on the correct power cord set to use with the

monitor, refer to the

Power Cord Set Requirements on page 46 in Appendix C.

WARNING! To reduce the risk of electric shock or damage to the equipment:

• Do not disable the power cord grounding feature. The grounding plug is an important safety feature.

• Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.

• Disconnect power from the product by unplugging the power cord from the electrical outlet.

For your safety, do not place anything on power cords or cables. Arrange them so that no one may

accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from the electrical

outlet, grasp the cord by the plug.

To reduce the risk of serious injury, read the Safety and Comfort Guide. It describes proper workstation,

setup, posture, and health and work habits for computer users, and provides important electrical and

mechanical safety information. This guide is located on the Web at

http://www.hp.com/ergo and/or on

the documentation CD, if one is included with the monitor.

CAUTION: For the protection of the monitor, as well as the computer, connect all power cords for the

computer and its peripheral devices (such as a monitor, printer, scanner) to some form of surge

protection device such as a power strip or Uninterruptible Power Supply (UPS). Not all power strips

provide surge protection; the power strips must be specifically labeled as having this ability. Use a power

strip whose manufacturer offers a Damage Replacement Policy so you can replace the equipment, if

surge protection fails.

Use the appropriate and correctly sized furniture designed to properly support your HP LCD monitor.

WARNING! LCD monitors that are inappropriately situated on dressers, bookcases, shelves, desks,

speakers, chests, or carts may fall over and cause personal injury.

Care should be taken to route all cords and cables connected to the LCD monitor so that they can not

be pulled, grabbed, or tripped over.

4 Chapter 2 Safety and Maintenance Guidelines

Maintenance Guidelines

To enhance the performance and extend the life of the monitor:

●

Do not open the monitor cabinet or attempt to service this product yourself. Adjust only those

controls that are covered in the operating instructions. If the monitor is not operating properly or

has been dropped or damaged, contact an authorized HP dealer, reseller, or service provider.

●

Use only a power source and connection appropriate for this monitor, as indicated on the label/

back plate of the monitor.

●

Be sure the total ampere rating of the products connected to the outlet does not exceed the current

rating of the electrical outlet, and the total ampere rating of the products connected to the cord does

not exceed the rating of the cord. Look on the power label to determine the ampere rating (AMPS

or A) for each device.

●

Install the monitor near an outlet that you can easily reach. Disconnect the monitor by grasping the

plug firmly and pulling it from the outlet. Never disconnect the monitor by pulling the cord.

●

Turn the monitor off when not in use. You can substantially increase the life expectancy of the

monitor by using a screen saver program and turning off the monitor when not in use.

●

Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked

or covered. Never push objects of any kind into cabinet slots or other openings.

●

Do not drop the monitor or place it on an unstable surface.

●

Do not allow anything to rest on the power cord. Do not walk on the cord.

●

Keep the monitor in a well-ventilated area, away from excessive light, heat or moisture.

●

When removing the monitor base, you must lay the monitor face down on a soft area to prevent it

from getting scratched, defaced, or broken.

Cleaning the Monitor

1. Turn off the monitor and the computer.

2. Unplug the monitor from the wall outlet.

3. Clean the monitor plastics with a clean cloth dampened with water.

4. Clean the monitor screen with an antistatic screen cleaner.

CAUTION: Do not use benzene, thinner, ammonia, or any other volatile substances to clean the

monitor or the screen. These chemicals may damage the cabinet finish as well as the screen.

Shipping the Monitor

Keep the original packing box in a storage area. You may need it later if you move or ship the monitor.

Maintenance Guidelines 5

3 Setting Up the Monitor

To set up the monitor, ensure that the power is turned off to the monitor, computer system, and other

attached devices, then follow the instructions below.

NOTE: Be sure the master power switch, located on the rear panel of the monitor, is in the off position.

The master power switch turns off all power to the monitor.

Installing the Monitor Pedestal Base

NOTE: Do not install the pedestal base if the monitor will be used on a wall, swing arm, or other

mounting fixture; instead see the section on

Mounting the Monitor on page 17 in this chapter.

1. Using both hands, position the monitor over the pedestal base.

CAUTION: Do not touch the surface of the LCD panel. Pressure on the panel may cause non-

uniformity of color or disorientation of the liquid crystals. If this occurs the screen will not recover

to its normal condition.

2. Press down firmly on the monitor to lock the pedestal base in place. When the base locks, it will

make a clicking sound.

Figure 3-1 Inserting the Monitor into the Pedestal Base

NOTE: Be sure the pedestal base is securely locked before continuing with the setup.
